- 【2-in-1 Professional Diagnostic Tool】Battery & Relay Testing - Not just a battery tester. The KONNWEI KW371 integrates an advanced 12V/24V relay tester capable of diagnosing 4-pin and 5-pin automotive relays. Quickly identifies coil failures and contact wear without disassembling the entire fuse box—a must-have for mechanics and advanced DIYers.
- 【Wide Compatibility for 6V/12V/24V Batteries】 - Unlike testers limited to 12V, the KW371 covers 6V (Motorcycle), 12V (Car/SUV), and 24V (Truck/Boat) systems. It accurately analyzes Lead-Acid, AGM Flat/Spiral, Gel, EFB, and Lithium batteries with a 10-2000 CCA and 5-220 Ah range. Supports multiple global standards including CCA, JIS, EN, DIN, SAE, IEC, and GB.
- 【Cranking & Charging System Analyzer】Know Your Vehicle‘s Full Health - Perform 3 in-depth tests: Battery Health (SOH, SOC, Internal Resistance, Voltage), Cranking Test (Min/Max starting voltage & milliseconds), and Charging Test (Loaded/Unloaded ripple detection). Instantly determines if the issue is a dead battery, faulty alternator, or failing starter.
- 【User-Friendly with Clear Visual Alerts】 - Features a graphical waveform display for real-time voltage monitoring. Delivers straightforward results: Good Battery, Replace, Bad Cell, or Charge Retest. Polarity reverse protection ensures safety for beginners. Includes 18 language options (English, Spanish, French, etc.) for global usability.
- 【Rugged & Ready for the Field】No Batteries Needed - Powered directly by the vehicle‘s battery via durable alligator clips. Supports USB connection to PC for software updates and report printing (Windows supported). Designed for mechanics, fleet managers, and RV/boat owners who demand reliable diagnostics on the go.
